Note: Don't be intimidated by all these functions! Most users, including myself,
will only use simple math in Calc Pages most of the time! However, for those
who study or work in math or science, it is nice to know that all these functions are
available. Other specialized functions, like financials and statistics, are likely
to be added in the near future.

Tip: Copying and Pasting from CalcPages

You can copy and paste your calculations and results into other
programs such as emails, Word documents, or even Excel.
However, if you copy and paste directly from the table where
the expressions are edited you will find that the results aren't
very satisfying, since "text boxes" will be pasted into your target
documents. This is probably not what you would want!

To improve the copy and paste functionality, you can switch the
Calc Page into "Text View" by clicking the "Text" button (see
image). From "Text View" you can highlight and then
copy andpaste. Your results using this technique should be
much better.
You might want to resize the browser window before copying.
Click the "Edit" button to return to the normal CalcPages view.
